What Stewarts Law does

Stewarts Law LLP is the UK's largest litigation-only law firm, founded in 1990 and headquartered in London with a second office in Leeds. The firm specializes exclusively in high-value, complex disputes across 22 practice areas, including aviation, commercial litigation, competition litigation, divorce and family, employment, fraud, insolvency and asset recovery, international arbitration, international injury, medical negligence, personal injury, policyholder disputes, securities litigation, tax disputes, and trust and probate litigation, plus specialized units covering ESG disputes, group actions, investigations, non-performing asset recovery, professional negligence, sports disputes, and costs and funding disputes. By operating as a litigation-only firm, Stewarts maintains a conflict-free position that allows it to represent clients against global banks and multinational corporations that other firms with broader transactional practices cannot act against.

The firm's client base spans FTSE 100/250 and Fortune 500 corporations, sovereign wealth funds, governments, institutional investors, and high-net-worth individuals across multiple jurisdictions including the UK, Europe, Middle East, India, Asia-Pacific, Africa, the Americas, and offshore centres. Notable mandates include defending Aiteo in a US$ multi-billion ICC arbitration, acting for Vattenfall in a multi-million Euro cartel damages claim against power cable manufacturers, pursuing a GBP 1bn claim against Glencore, securities litigation for institutional investors in the RBS Rights Issue (313 institutions) and Tesco misreporting claim (58 institutions), and aviation accident litigation against Boeing. The firm has recovered more than GBP 1.3bn in damages over the last decade for clients and has served approximately 4,500 clients through alternative funding arrangements across 2,000+ disputes.

Stewarts generates revenue through professional services fees on a quote-based model tied to case complexity, with innovative costs arrangements including conditional fee agreements, after-the-event (ATE) insurance via the Stewarts Litigate facility (operated with Arthur J. Gallagher), third-party litigation funding, and risk-sharing fee agreements. The firm employs 450+ staff including 97 partners and 200+ lawyers across its specialist areas. Its technology stack is standard legal practice tooling with no proprietary platforms disclosed; the firm markets primarily through legal directory rankings (Chambers, Legal 500), industry awards, and thought-leadership content, and distributes services directly through its offices and a strategic alliance network of international law firms for cross-border coordination.
